I remember this game being impossible to find when it first came out, and I don't even know if you can get it anywhere anymore short of the used bargain bin (might not even find it there either). It's almost collective rare I think, except not actually that valuable... right now.

Yeah it was a bit easy, but I believe the last few tracks of the game do get rather tricky in their own regard. For me personally the difficulty was just fine since I never really had enough interest in the DDR games to get really into them, yet I'm really competitive, so it wouldn't have sat well with me if I couldn't beat the REALLY hard songs on the regular games.
